This week, Emma and Darius talk making music on the tiny computer you probably carry around everywhere in your pocket. We cover the history of making music on mobile devices going all the way back to the retro Palm Pilot, consider mobile music as an on-rails, beginner-friendly way to get into the sometimes intimidating world of music production, and ponder why there are so few music apps available for the mobile operating system used by nearly ninety percent of the world. Links: An interview with Emma on mobile music-making, a discussion of the history of mobile music-making on Palm OS devices, and Emma's list of apps to get started making music on mobile.
